WHEEL FOR ROAD-VEHICLES.

SPEGIFIGATIQN forming part of Letters Patent No. 685,174, dated October 22, 1901.

Application filed March 5, 1901. Serial No. 49,761. (NomodeL) To all whom it may concern:

Be it known that I, CHARLES RENARD, clockmaker, of 33 Rue Oambon, in the city of Paris, Republic of France, have invented Improvements in Wheels for Road-Vehicles, of which the following is a full, clear, and exact description.

This invention relates to an improved wheel-telly provided with a detachable rim, and is chiefly applicable to the vfellies of the wheels of vehidles having pneumatic tires.

My invention is principally characterized by the combination, with circular channels formed in the felly, of one, two, or more Wires arranged in such a manner as to permit one of the edges of the telly to be withdrawn for the purpose of quickly and easily detaching the tire.

In the accompanying drawings I have shown as an example only the arrangement which forms the subject of my invention.

In the drawings, Figure 1 shows in elevation a portion of my improved felly as applied to a metallic wheelfor example, a velocipede-wheel. Fig. 2 is a plan view corresponding to Fig. 1. Fig. 3 is a transverse section takenvon the line A 13, Figs. 1 and 2. Fig. 4 shows in transverse section my improved felly as applied to a wooden wheel.

Like letters of reference indicate corresponding parts throughout-the drawings.

As shown in Figs. 1, 2, and 3, myimproved wheel-telly comprises,in principal,the folly, properly so called, a, provided near one of its edges with an annular channel which registers with another corresponding annular channel formed in the rim 6 of this felly. In the rim 1) is arranged one, two, or more apertures c for the passage of one, two, or more wires 01.

The mounting of the pneumatic tire 6 upon the telly is accomplished in the following manner: The tire e is placed upon the fell y a, and the rim 1) is then put in place. Afterward one end of the wire d is introduced through the appropriate aperture into the circular channel. By then turning either the felly or the rim the wire is led into the channel until its foremost end is almost reexpo'sed -that is to say, until the wire (2 is completely lodged in the circular channel. The assembling of the parts being efiected as here'- inbefore set forth, if alateral tractive force is applied either to the folly or to the rim it is impossible to separate these two parts by reason of the resistance or locking aiforded by the wire in the channel. If it is desired to remove the pneumatic tire, it is only necessary to turn one of these parts-i. e., the felly or the rimin the contrary direction to that in which it was formerly turned. This move ment is transmitted to the wire, which passes out of its aperture, and after it has been withdrawn the'rim can be taken away and the pneumatic tire removed.

It will be understood from the preceding that the mounting and detaching of the telly can be rapidly and easily elfected.

When my improved felly is applied to a wooden wheel fas shown, for example, in

Fig. 4=-the rim 1) instead of being applied upon the inside of the telly, as in the arrangement previously described, is applied to the outside in order to facilitate itsmounting and removal.

It is well understood that the improved fell y which I have described can carry one or two detachable rims and can be provided with one, two, or more annular channels in which one, two, or more corresponding wires can be lodged.

I can, if desired, vary the forms, dimensions, details, and materials employed in the construction of my improved telly without departing from the nature of my said invention.

I claim- 1. An improved wheel-telly, provided with adetachable rim for wheels of vehicles having pneumatic tires,characterized by the arrangement of annular channels formed in any number in the felly a and in the rim 1) at the bearing-points, such channels being kept in relation by means of wires (1, so that the parts a and b can only be separated after the removal of the wires d.

2. Awheel having its rim formed in two an nular parts arranged jointly to hold the tire and formed with annular matching grooves or channels, one of said parts being provided with an aperture leading to the grooves, and a flexible annular locking device adapted to be introduced through said aperture into the said matching grooves, to hold said parts of I ing the channels and serving removably to I0 the rim together. hold said parts of the rim together.
